Definitions
- the invention relates to an air-conditioned switching cabinet with wall elements and at least one cabinet door, as well as an air conditioning unit and / or heat exchanger.
- the air conditioning unit forms a separate unit from the switchgear cabinet, which has to be placed on the switchgear cabinet and brought into air-conducting connection with the interior of the switchgear cabinet.
- the top wall of the control cabinet must be provided with openings which are connected to the air intake opening and the air outlet opening of the Air conditioning unit are brought to congruence, as shown for example in DE 37 10 566 and DE 37 35 551 Cl.
- Such a configuration of a switchgear cabinet is particularly suitable for retrofitting the switchgear cabinet with an air conditioner, but requires an increased expenditure of parts for the air conditioner designed as a separate unit.
- Control cabinets or control cabinet walls are also known, in which an air conditioner (or components thereof) is (are) installed in the interior of the cabinet body or frame of the control cabinet, as shown in DE 88 07 768 U1.
- an air conditioner or components thereof
- this design of an air-conditioned control cabinet has the disadvantage that space for internals is lost in the interior and that subsequent air conditioning of a fully equipped control cabinet is no longer possible.
- This object is achieved according to the invention in that the air conditioning unit and / or the heat exchanger is integrated in a wall element or the cabinet door, the wall element or the cabinet door being designed as a housing for receiving the components of the air conditioning unit and / or the heat exchanger.
- control cabinet and the air conditioning unit and / or the heat exchanger generally form a delivery unit which leaves the interior of the user free for complete installation.
- the wall element or the cabinet door, together with the air conditioning unit and / or the heat exchanger form a further unit which can be produced cost-effectively and which can be retrofitted at any time as a replacement for a wall element or the cabinet door of a non-air-conditioned control cabinet.
- a fully equipped control cabinet can be subsequently provided with air conditioning via an air conditioning unit and / or a heat exchanger.
- the wall element or the cabinet door delimits a receiving space which adjoins the interior of the frame or the cabinet body, then the interior is simply enlarged to the outside and the wall element or the cabinet door retains the original function as a conclusion of the control cabinet, but forms the housing for receiving the components of the air conditioner and / or the heat exchanger.
- a further embodiment provides that the components of the air conditioning unit and / or the heat exchanger are connected and wired to one another ready for operation.
- the air conditioner and / or the heat exchanger then only needs to be connected to the power supply of the control cabinet.
- the air circulation in the control cabinet can be influenced in a targeted manner in that the components of the air conditioning unit and / or the heat exchanger to the interior of the cabinet body of the frame are covered by a cover and that when an air conditioning unit is integrated, the cover is provided with air intake openings and air outlet openings is or that when integrating a heat exchanger, the cover with air inlet openings and the wall element or the cabinet door are provided with air outlet openings.
- Fig. 1 shows schematically an open cabinet with frame, in which an air conditioner is integrated in a wall element, and
- Fig. 2 shows schematically an open cabinet with cabinet body, in which an air conditioner is integrated in the cabinet door.
- FIG. 1 shows a control cabinet with a frame 10, which is closed on three sides by means of a base plate 17, a cover plate 18 and a wall element 19.
- the limited by the frame legs 1 1, 13, 14 and 1 5 The front of the frame 10 is closed by a cabinet door 30.
- the cabinet door 30 is hinged to vertical frame legs 13 by means of hinges 32 and can be fixed in the closed position by means of a lock 31.
- the cabinet door 30 can be stiffened on the inside by means of an attached door frame 33.
- the cross-sectionally trapezoidal wall element 20 with the inclined wall parts 21 and 22 forms a trough-like housing in which the components 23, 24 and 25 of the air conditioner and / or the heat exchanger are installed, so that an integrated structural unit is created which acts like a normal wall element 19 can be connected to the frame 10.
- the components 23, 24 and 25 can be covered in the wall element 20 by means of a cover which is provided with air intake and air outlet openings.
- the correspondingly designed components of the air conditioning unit can be connected directly behind it.
- the cover can be provided with inlet openings and the wall element 20 with air outlet openings.
- the arrangement of the air inlet openings and air outlet openings and the distribution of components 23, 24 and 25 determine the circulation of the air in the heat exchanger and are carried out in a known manner.
- a cabinet body 10 can also be used, which is only open at its front, as shown in FIG. 2.
- the cabinet door 30 is designed as a housing for the components 23, 24 and 25 of the air conditioner and / or the heat exchanger.
- the Cabinet door 30 with integrated air conditioning unit and / or heat exchanger is then articulated on the cabinet body like a normal cabinet door.
- the air-conditioned control cabinet is provided with an air conditioning unit and / or heat exchanger integrated in the cabinet door 30 as a delivery unit and can be obtained with components that are connected and wired ready for operation.
- the cabinet door with integrated air conditioning unit and / or heat exchanger can also be reordered as a structural unit and used for the subsequent air conditioning of a fully dismantled and equipped control cabinet. Only the cabinet door needs to be replaced.
